Gold factory process flow chart

The process flow chart of a gold factory typically includes the following steps:

Mining: The gold ore is extracted from the mine using various methods such as underground mining, open-pit mining, or placer mining.

Crushing: The ore is crushed into smaller pieces to facilitate the extraction process.

Grinding: The crushed ore is then ground into a fine powder using a ball mill or other grinding equipment.

Gravity separation: Gold is often found in association with other heavy minerals such as pyrite, and gravity separation is used to separate the gold from the other minerals.

Flotation: Flotation is a commonly used method to separate gold from sulfide minerals such as pyrite and arsenopyrite. The process involves adding a reagent to the ground ore to create a froth that floats to the surface, which can then be skimmed off to collect the gold concentrate.

Cyanidation: Cyanidation is a process in which gold is leached from the ore using a cyanide solution. The gold-containing solution is then treated with activated carbon to adsorb the gold, and the resulting carbon-in-pulp (CIP) or carbon-in-leach (CIL) process is used to extract the gold.

Refining: The gold concentrate is then further refined to remove impurities such as silver, copper, and other metals. This can be done through various methods such as electrolysis or chemical precipitation.

Smelting: The refined gold is then melted down and cast into bars or other forms for storage or sale.

The above steps may vary depending on the specific characteristics of the gold ore and the processing plant, and additional steps such as roasting or bioleaching may be required for certain types of ores.
